Documentation

Provides an Emacs-style autoload facility which takes the basic form

[syntax](autoload unit procedure-name ...)

such that the first time procedure-name is called, it will perform a runtime require of 'unit and then apply the procedure from the newly loaded unit to the args it was passed. Subsequent calls to procedure-name will thereafter refer to the new procedure and will thus not incur any overhead.

You may also specify an alias for the procedure, and a default procedure if the library can't be loaded:

[syntax](autoload unit (name alias default) ...)

In this case, although the procedure name from the unit is name, the form defines the autoload procedure as alias.

If the library can't be loaded then an error is signalled, unless default is given, in which case the values are passed to that.
